Abstract: The present disclosure describes multi-well plates comprising a frame made of a first material having an array of a plurality of holes arranged in a columnar pattern on the top surface and an array of segmented breaking features arranged in a linear columnar pattern which alternates with the columnar pattern of the plurality of holes, and a plurality of tubes/wells made of a second material placed into the plurality of holes, wherein the multi-well plate is manually divisible along the segmented breaking features into one or more columns of multi-well/tube strips. Manually dividing multi-well plate of the disclosure produces multi-well strips or segments that have smooth edges, thereby reducing injuries and glove tear incidences.

Abstract: This invention relates to a mould tool and method for forming a polypropylene PCR plate comprising a channel, a main body and an overflow area; wherein the channel is configured to facilitate the introduction of molten plastics material into the main body and wherein the main body is configured to facilitate the flow of the said molten plastics into the overflow area once the main body of the mould tool has been filled with the said molten plastics.
